Snakeoil OS: The Blog

Here’s an interesting problem, wondering how many of you out there use PCD and got stuck trying to add an ESXi host?

If you use CLI and look at the tomcat logs you will see this error:

If you see this error, it’s because your root password of your ESXi machine is more than 15 characters long. Shortern the root password to 15 and under and Bob’s your uncle! I’ve googled this for days and didn’t find the solution.

Hoping this will quickly help somebody who faced the same problem.

Introduction

Audiophile grade fuses, what are they and what are they used for?

In a nutshell a fuse is:

an electrical device that acts as a sacrificial device to provide over current protection.

i.e. a fuse is something that will blow itself up when electrical current exceeds a pre-defined threshold.

This act of self sacrifice breaks the electrical circuit and this prevents everything behind the fuse from catastrophic damage (i.e. certain death).

An audiophile grade fuse simply put is an item constructed from components and materials with a single goal in mind - uncomprosing audio quality. The term “Fuse Rolling” involves replacing the stock fuse with a different fuse (not necessarily an audiophile grade fuse) to influence the sound signature of the audio system.

An example of an audiophile grade fuse is the TF Series Fuse from Furutech, pictured here.

Whether fuse rolling is something you should consider is subjective. Read on to find out if audiophile fuses is a thing for you.

UPDATE 2: 15 Sept 2016 : Comments and contact are working again. Talk about weird.

UPDATE 1: 15 Sept 2016 : After a software update Contact me is broken again!  If you need to contact me sign up to the forums and post a thread. 

Apologies if you guys have sent me emails via the “Contact” option on the top menu and I didn’t get back to you. All the mails via the “Contact” have been forwarded to the spam folder. I was flat out last month so didn’t check the spam folder until today .

I’d start replying to the mails tomorrow afternoon.

Contacting me from the blog system should now be fixed, but it’s best to sign up to the Snakeoil forums and post a thread if you have any support questions.
